Table data type not using the table config fix

What was the issue? 

When you define initial data for the Table data type, that data wouldn’t be loaded when you create a new object.

How did you solve it? 

This was caused by a bug inside Javascript because the check was done on an empty array and the empty array is not a false value in Javascript. So I changed that check to a proper one.

Why is this fix important?

This is important because now the Table data type will work as it's supposed to work and initial data is going to be loaded when creating a new object.
